The Strip supply-roll, casing is connflctfldfll u an enclosing and, protecting relation the j main casing. H l "a0 a 1 guidew-a'y =6, consist-ingot an upperai idlovw er, member,the strip traveling between them.

It will be seen that feeding roller 10 will thus rotate in exact predetermlned red lationewith the rotation of ratchet wheel 17,

and that by variablypredeterminable actuag --tjions;of the ratchet wheel, variousjdesired feedsofthe strip y f t at feed roll 1 0. "The roll- 10 is proportioned in connection. with'the actuating means to feed unit lengths of the strip, corresponding to the length of the tickets or; stamps in the strip;

The actuating means for ratchet wheel 17 coin Lifses a hand lever loosely, mounted onfifiagshaft 18, and projecting outwardly through anarcuate slot 26 formedinthe top pm of the; cylindrical 'msing Pivdtlfliy consisting of two parts, one on eitherqside- "the fiat upper strip toresi its uppermost position. a Fixed to the handxed mewe -m0unted on, the lever 25 at 27 is a pawl 28 adapted to engage with the teeth of the ratchet wheel 17, and normally impelled into engagement therewith'b a spring '29, mounted on'the hand-lever an pressing'against the the pawl '28. The embodied'm'eans for v determining-the ratchet tooth which the pawl 28 shall engage; on any given dispensing operation (and consequently the extent of ro- .tatign ofrthe' ratchet; wheel. 17 and, feeding drum 10, and the length Qfstrip thereby; fed

and emitted), comprisesa hand-lever 37 projectingupward'ly through an arcuate slot 38 formedin'the top of the cylindrical casing,

The lever 37 has fixed thereto an arcuate shield 39,-whichfextendsover the ratchet teeth of the wheel 17 (Figs 1 and 3) andshields a greateror less number of theiratchet teeth fromengagement mounted as thezupper; art of thelever 37 a hand piece 45, lying at against the'upper crating with theseipositioning means, there'is part of the-lever and longitudinally, slidab'ly connected thereto by pin and slot connections 46. v The pins are impelled to'the upper ends I ofztheir slots by means of a bent-spring 47, mounted on the lever 37 and 1pressing against 'ently hold it at piece 45 is a' in/t9, which acts as astop in co-. operation with the notches 42. Pinn49'v :projects through a slot in the lever 37 and is adapted tozengage by. the action of the spring 47 with the strip 41 and to enter anyone of the notches 42 when the hand-piece 45 is released,

and to hold the lever 37and therewith the;

Thisinsures positiwe-zfeed-of the strip in con "nectioniwith the positive feedof-the feed roller provided by the mechanism. In the embodied form thereof, a cooperating roller 51, spring-pressing the strip against roller 10, is mounted in the side plates of aiframe '52, which "hameis pivotally mounted on a cross 3 51 a gear-wheelfj58,'iwhich' -meshes*with an; idler gear 59 -Whieh innturnvmeshes with an idler gear 60, Whiohfmeshes with a gear 61; y I i v V "is gniov'ed forwardlyduring:thestrip -fee'ding l1 shaft or rod'53 fixed'in'andpfbjecungimm the frame structure. 1 A spring 54, mounted atf 55 on the fixed frame struoture pressesagainst the part5 6-of this pivoted frame; and thereby presses the roller 51' against therollerf 10..
